Be it known that L VfiLLiAM PRELLWITZ, e Citizen oi' the United States, end e residentol lhillipslnirg, in the county of Warren und State of New Jersey, have invented n new und use/inl Improvement in Channeling-Mnchines, of which the `following is e specification.

The principal ohjeet ol this invention is to provide a chnnneliiig-machine which is adopted to;- nse ns i1 straight-line chenneler and when it hns reached e predetermined point is adapted for use es o. redini ehnnneler, wherel v the drill-tool muy be unused to strike the rock :it right :ingles thereto 'instead of Iit en nente angle, :is has heretofore been neeessai?r when the trnnsl'er ents have been made With n regular straight-line ehnnneler.

A in; ther ohjeet of 111:Y invention is to provide certain iniprmf'enients in the construe lion, l'ofni, :ind arrangement of' the several pints, whereby the rmlially-swinging shell whieh supports the drill carries the sector, :ind the trunsversely-swinging freine which is hinged on the truck carries the worm, the. worin heine driven troni n rnotor carried on the truck iin'lependentotx the motor which drives the truck along its track.

A further object is to provide n. machine of the nhove character in which n very extended und rigid support for the shell on its freine is provided.

instance three-cylinder'rotary engine, is f shown mounted on the truck l, sind it er ranged to drive the trnek along' the traelr.

when the nieehine is to he used its e straightline chnnneler.A The connection of thi inotor with one pair of traction-Wheels is in the nsunl mannerthrough a ,gemeend-Worin eennection 6, 7 S, and 9 with the axle i0, which is fixed to the said pair of Wheels. tor 5 is herein shown :is being provided with a hond-operated reversing and controlling` lever 1i for controlling the engine, end thereby the movement of the truck along the track. The truck may he provided with the usuel elnniningdrons 12, which are arrnnged to engage the heads of the track-reds 'for locking the ehonneierto the rails when it has heen moved to :t predetermined point.

The drill is denoted as e. whole hv 13, and it may be ol' any well-known or approved forni end is herein shown es ot' the tinidpresw sure-controlled type. This drill is carried h v e shell'l, which is arranged to be moved forwardly and rearwardly in n` radial direction on the i'raine l5, which is hinged to Ythe truck i nt 16 to swing transversely'thereof into (.lilerent adjustments. This freine i5 :muy he adjusted to different angular positions with respect te the truck by ineens oi. the usuel hand-nut i7, carried by ose/inging erm 18, hinged to the trnelt, which hond-nvt engages o screw-holt i9, hinged to the banni ot' the frame 15 et its upper portion.

The shell i4 oi the drill is pivoted to the truelefr'mne i5 es follows: The shell i4 is provided with a reverse" eene ,20, which is sented in n. halt-recess 2i in the traine 15. The other halt oi. the cone-reeess is formed in the end ot n. movable jow 22, 'which is ,fitted -to slide towerd and away from the pivotcone 2O h v having its vsides engeging undereut side Wells 24 of e vertical groove 25,

plane oi' the line l) D of Fig. e, and e portion i opening inte the half-recess 21.

The ino IOO cone'2() by providing the'shell with oppof The shell n14 is guided and supported by the frame 15 uponopposite sides ofthe pivot- Sitelyfarranged upper and lower segments-26 27, which are provided with lips-28 29, which are located in concentric recesses() 3l in. the frame 15. These upper and lower segments 26 27 are 'bolted rigidly to the shell le. l

The shell 14 is locked against movement when desired by providing a bolt, the laterally-projecting arms 32 33 of which rest in sockets 34 35 in the frame l5 and the vertical portion 36 of which boltl projects through a rearwardly-extended arm 37 oi' the movable jaw 22. Below this arm 37 of the jaw l the T-bolt is provided with a. nut 38. When this nut 38 is set up, ,the jaw 22 will he ,i Y broughtlinto snug engagement with the cone ZAQand clamp it securely and rigidlyT 'to the framewwi. v Y

The means which l have shown forswing lng'the drill when it is desired to use the machine as a radial channeler is constructed, aru

ranged, and operated as follows: The upper segment/r2@ hereinhefore referred to, is pro-, vided with a' segmental rack 39, the teeth of 5 Which are at all times in mesh with a worm 4i), the shaft 41 of which is mounted in suitahle bearings 42 43 on the frame i5. A. motor 44 is mounted on the truck l, which motorin the present instance is shown as a three-cylinder rotary engine. This engine is provided with a hand-lever 45, arranged 1 to control thelnovement ol` the engine m l both directions.

An extensible and con,

tractible shaft i6 47 has a geared connection 4,8 49 with the engine elli and a geared connection 505i with a cross-shaft 52, mounted in suitable bearings in the frame l5 adjacent to the shaft 41. This shaft 52 has a geared connection 53 54 with the worm-shaft fil, so that the operation of the engine 44 will rotate the worm 40, and thereby swing the drillshell. This shaft 52 may he rovided with a handle 55 for use in manual y swinging* the drill ,when so desired.

The means for feeding motive power to the drill 'and 'to the motors hereinhefore descrihedvllas not been illustrated herein, as it is not thought that it is necessary for the clear understanding of the invention, and it forms no. part of the present invention.

@ne method of operation is as follows: The drill-tools for cutting the vfirst stage toward the lower level are secured in position for use.

The motor 5 is then started for the purpose of moving the machinealong-its tracks, and the drill is also put into operation-. Y` Ylfhcn the machine reaches the point indicatedinV broken lines at a in Fig. 3, the motorA 44 is put in operation, and the swinging` movement v of the drill is controlled by the handle of the motor for channeling from the point a to arc of a circle to cause the drill the channel from said predetermined point. no

the point a The truck may thenhe moved hack to its original-position. After the cnt- 65 at'the different stages b b c c d d e e"until 7o the machine has cut to the predetermined.

lower level f g. After this level 'has been reached the machine when being used as a radial cutter may cut out the rock by a series of operations, es shown in dotted lines in Fig. 3, beginning withff, to extend the level f through to the limit of the cut at g.

It' so desired, the drill-shellmay he locked to the truck-frame when the machine is heing used as La straight-line ohanneler and re- 8o l leased when used as a` radial cutter, Also the truck may he clamped to the track-rails vwhen the machine is used as a radialcutter. A

.it will he seen that the concentric guides in the frame for the upper and lower segments on the shell serve to materially brace the shell and produce a much stronger and more rigid construction than has heretofore heen ossihle at this point. It will also he seen t iat the extensible and contractihle con- 9o predetermined point and a motor connectedoo...

to the drillior swinging it in the are ofc circle to cause the drill to complete the channel lfrom said predetermined point.
